A bit of an interesting question, I know, but this is causing me serious difficulty!

I am a couple of weeks after birth, and breastfeed my child. During the day, I put pads in my bra to stop my breasts leaking milk. The problem is when I go into the shower, and it is nearly time to feed the baby, and my milk starts to leak.

Is there any way of plugging the breast for 20 minutes or so, while in the shower?
